force problems word problems with solutions

. As the hydrogen atoms come closer, the attractive force tends to decrease the potential energy of the system. When the potential energy reaches a minimum value, sharing of electrons take place between the two, resulting in a covalent bond. This stage is represented by the distance 'r o ..

1. The Earth's gravitational force causes an acceleration of 5 m/s 2 in a 1kg mass somewhere in space. How much will the acceleration of a 3kg mass be at the same place? Solution: The acceleration produced in any body due to the gravitational pull of the Earth does not depend on..

1. Calculate the force of attraction between Earth and the Sun. Solution: Given Mass of the Sun =10 3 2 kg Mass of the Earth = 6x10 2 4 kg Distance between the Sun and Earth = 150x10 9 m..

Force of Gravitation - Drop a stone from a height. What do you observe? The stone which was initially at rest starts moving towards the ground and attains a maximum speed just before it touches the ground. The stone is not moving with uniform speed. Its speed keeps changing at every insta..

Force of Gravitation - What do you observe when you drop a stone from a height? The stone which was initially at rest starts moving towards the ground and attains a maximum speed just before it touches the ground. Is the stone moving with a constant speed? No, it is not moving with unifor..

Force = 980 N Time for which the force acts = 0.1 s Change in momentum = impulse = Ft Therefore, change in momentum = Ft = 980 x 0.1 = 98 ..

Mass (m) = 10 kg Acceleration (a) = 7m/s 2 Force = 70 kgm/s 2 Force = 7..

W = F x S Force acting on the object is given by F = mg [Newton's second law of motion] Mass of the object (m) = 5 kg Distance moved = 2m Therefore, Work done = F x S = 98 J 02. How much work is done, when a force of 25 N displaces an object through 10 m, in the direc..

Work done (W) = 250 J Force applied (F) = 10 N Distance (S) = ? W = F x S Distance covered = 2..

(i) Create laws/legislation to force the reduction of air pollution e.g. strict automobile emission standards. In the National Capital Region of Delhi, the pollution laws state that all vehicles being sold have to confirm to Euro-II emission standards, vehicles have to use unleaded fuel ..
